There is NO BENEFIT in my knowledge using a DC tank instead of an AC tank.
Others correct me please if I am wrong.

Regardless of how you charge the primary capacitor, it will assume a certain
polarity (different during different AC cycles, of course). At bang time this
voltage will oscillate (that is, you'll get IN ANY CASE AC voltage and
current).
And that is just what makes all the TC work.

If you wanted to regulate the charging voltage, to achieve repeatibility and a
certain degree of precision, than you'd use a DC supply. Just to get rid of all
those AC / RSG phase dependance and to get a repeatable bang. I bet you are not
aiming at that, aren't you?
